DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vertical ice making machine, and more particularly, to an ice making room comprising a plurality of ice making compartments opened in the horizontal direction.
A water tray having a fountain port for supplying ice making water to each of the ice making compartments.

[0002]

2. Description of the Related Art A vertical ice maker shown in FIG. 8 is disclosed in Japanese Patent Application No. 6-600 filed on Mar. 4, 1994 by the present applicant.
An ice maker described in the specification of No. 30. The purpose of the invention of the prior application is to reduce the "folds" connecting the ice pieces to each other and to reduce the "dents" formed on the surface of the ice pieces. In order to achieve this, the ice making machine is provided with a plurality of ice making compartments, each of which is open in the horizontal direction and inclined downward toward the opening side, and a vertically arranged ice making compartment 1; An ice making water tank 13 and a water tray 9 which is disposed adjacent to or in contact with the opening side of the ice making compartment, has a fountain 7 for the ice making compartment, and receives return water from the ice making compartment.
And a circulating pump 15 for guiding the ice making water in the ice making water tank 13 from inside the water tray 9 to the fountain port 7.

[0003] The ice making chamber 1 has a plurality of ice making chambers 5 defined by partition plates extending vertically and horizontally in a grid pattern. Of the partition plates, the horizontal partition plate 3 is inclined downward by a predetermined angle from the horizontal direction from the back side of the ice making chamber 5 toward the opening side. Thus, during the deicing process, the ice in each ice making compartment is easily separated by its own weight and falls into the ice storage. On the other hand, the wall 11 of the water tray 9 that closes the opening of each ice making chamber 5 when it is in the closed position as shown in FIG.
A plurality of fountain ports 7 corresponding to the respective ice making chambers 5 are provided in the horizontal direction, and ice making water in the ice making water tank 13 is pumped into the water tray 9 by the circulation pump 15, and each fountain port 7 Then, it is supplied to each ice making chamber 5.

FIGS. 9 and 10 are enlarged views of the vicinity of an ice making chamber, a water tray and a fountain having substantially the same structure as described above. Pressure chamber 11 in water tray 109
The ice making water flowing into the ice making water channel 115 from 3 is jetted from each fountain port 107 provided in the wall 111 to each ice making chamber 105 in the ice making room 101. The jetted ice making water flows in the ice making chamber 105 as shown by an arrow in FIG. Focusing on one ice making chamber, the ice making water breaks up and down after colliding with the back wall, but the area above the collision site in the ice making chamber is wider than the lower area, and the upper area In such a case, the water must flow against the gravity, and the ice making water may not reach the upper corner portion, particularly the deep upper corner portion a. Accordingly, since the actual progress of ice making is frozen from the portion near the evaporator 117, as shown by the ice making progress line in FIG. 10, the ice making first proceeds to the area 181, and further, the area 183 and the area 18
It progressed in the order of 5, and finally, even if the ice making process was completed, it was found that there was a region b where ice was not made in the upper rear corner portion a. In this case, since the deiced water has a defect in the non-ice-making region b, ice corresponding to the shape of the ice making compartment is not obtained, which is not preferable.

The vertical ice maker of FIG. 8 has a horizontal partition plate inclined, but the same phenomenon occurs in other vertical ice maker. For example, as shown in FIG.
In the case of a vertical ice machine in which the center axis of the ice making chamber is not inclined downward as described above and is oriented substantially horizontally,
The ice making water flowing into the ice making water channel 115 from the pressure chamber 113 in the water tray 109 is jetted from each fountain port 107 provided in the wall 111 to each ice making small chamber 106 in the ice making chamber 102.
The jetted ice making water flows in the ice making chamber 106 in a downward direction as indicated by an arrow in FIG. That is,
Focusing on one ice making chamber, the ice making water breaks up and down after colliding with the back wall, but must flow against gravity in the area above the collision site in the ice making chamber. The ice making water may not sufficiently spread to the upper corner portion c on the opening side. Therefore, since ice making proceeds from a portion near the evaporator 117, there is a region b where ice is not made in the upper corner c on the opening side. For this reason, the ice that has been deiced in the same manner as described above lacks the non-ice-making region b, which is not preferable as ice.

As is well known, ice produced by an ice maker is very widely used in various fields. In particular, restaurants and vending machines related to food and drink provide customers with excellent aesthetically pleasing ice. Due to the need, the above problem has been unfavorable for ice makers.

As a solution to this problem, the output of the circulating pump motor is increased to increase the fountain force, and the high pressure allows the ice making water to reach the upper upper corner a or the upper upper corner c of the ice making chamber. However, the increase in output increases the size of the circulating pump motor and the size of the ice making machine itself, which requires a large installation space. ) May increase, and another problem may occur.

[0008]

In the vertical ice making machine having the above-mentioned water tray structure, the ice making water supplied from each fountain port into each ice making room during the ice making process is transmitted to every corner of the ice making room. In some cases, the ice is not sufficiently distributed, and an area where ice is not produced occurs. Therefore, there is a problem that the ice removed from the ice making compartment has a defective portion and does not have a predetermined shape along the wall of the ice making compartment. Further, in order to prevent the above-mentioned problem, it is necessary to rely solely on the enlargement of the circulation pump motor, which causes another problem such as an increase in the manufacturing cost and operating cost of the device.

Accordingly, the present invention is to solve such a problem, and it is possible to make ice in a small ice-making chamber uniformly without increasing the size of a circulating pump motor, and to make ice of a preferable shape. It is an object of the present invention to provide a vertical ice machine that can be used.

[0010]

In order to achieve the above-mentioned object, a vertical ice making machine according to the present invention comprises a plurality of ice making compartments which are opened in a lateral direction, and an ice making compartment arranged in a vertical direction. The ice making compartment is provided with a fountain port for vertically opening and closing the opening of the ice making compartment between a closed position and an open position thereof to supply ice making water to each of the ice making compartments. A water tray for receiving return water from each of the fountains, wherein each of the fountains is such that when the water tray is in the closed position, ice making water from the fountain is supplied upward from the horizontal direction. In addition, a hole is formed in the water dish.

As a specific embodiment, in an ice making machine in which the center axis of each of the ice making chambers is inclined downward from the horizontal direction, the fountain port is provided substantially parallel to the center axis. I have.

Alternatively, an ice-making chamber having a plurality of ice-making chambers opened in the horizontal direction and arranged in a vertical direction, and a closed position and an open position of the opening to open and close the opening of the ice-making chamber. A water tray for receiving ice water from each of the ice making compartments, and a water tray for receiving return water from each of the ice making compartments. When the water tray is in the closed position,
The ice tray is provided in the water tray so as to supply ice making water to the ice making chamber above the center axis of the corresponding ice making chamber.

[0013]

The ice making water supplied to the water tray from above flows into the ice making channel inside the water tray, and is jetted upward from each of the fountain ports provided in the water tray into each ice making chamber. Therefore, since the injected ice making water has an upward acceleration component, the ice making water sufficiently spreads to a region where the ice making water is hard to spread, that is, the upper corner portion of each ice making room.

In a vertical ice making machine in which the center axis of the ice making chamber is inclined downward from the horizontal direction, if the fountain port is provided substantially in parallel with the center axis, the ice making water in the ice making chamber will be reduced. Of the upper corners that were difficult to spread, the ice making water sufficiently spread to the upper corners, which are particularly conspicuous.

Further, even when a fountain port is provided at a position close to the upper partition plate among the partition plates defining each of the ice making compartments, the upper region where ice making water is hardly distributed in each ice making compartment. Is supplied with ice making water.

[0016]

The ice making water can enter and exit from a gap formed between the a and the horizontal partition plate 203b. The direction in which the fountain port 207 is pierced is at least higher than the horizontal direction toward the ice making chamber 205. In the embodiment, the inclination angle of the fountain port 207 is set to be equal to the horizontal partition plate 203 b defining the ice making chamber 205 in the ice making chamber 201.
, And the axis of each fountain 207 is linearly aligned with the center axis of each ice making chamber 205. However, the orientation of the fountain port is not limited to the present embodiment, because there is an optimal state for each ice maker based on the relationship between the position, shape, dimensions, and the like between the fountain port 207 and the ice making chamber 205.

Below the ice making chamber 201, a mechanism for operating the water tray 209 is provided. Referring to FIGS. 1 and 2, first, a motor (drive device) is provided at a required position below the ice making chamber 201. At least one, in this embodiment, two cam levers 233 are attached to the motor shaft 231 which is the output shaft of this motor, with its base end fixed integrally with the motor shaft 231. That is, it is attached so as to tilt by the same angle as the rotation angle of the motor shaft 231.

A lever piece 235 is integrally fixed to the cam lever 233. A switch 237 provided on the frame 225 is on the tilt locus of the lever piece 235. A spring holder 233a is provided at the tip of the cam lever 233,

When the ice making process is completed and the deicing process is started, the water tray 209 is moved to the position shown in FIG.
As shown in FIG. Water dish 2 like this
When the valve 09 fully opens, the solenoid valve 247 opens, and tap water is supplied from the tip of the water supply pipe 245 into the ice making water tank 243 via the solenoid valve 247. The solenoid valve 247 is kept open for 90 seconds, then closed and the water supply is stopped once. When the ice in the ice making chamber 201 separates due to the progress of the deicing process, the temperature of the ice making chamber rises, so that
A sensor (not shown) provided in the water tray 209 detects the rise in temperature as completion of deicing, and the water tray 209 rotates from the inclined state shown in FIG. 2, ie, the open position, to the vertical state shown in FIG. 1, ie, the closed position. Enter the ice making process. When the water tray 209 reaches the closed position, the ice making machine enters the ice making process as described above, but the solenoid valve 247 keeps the valve opened further and closes 15 seconds after the water tray is completely closed. .

In the ice making process, referring to FIG.
The ice making water 241 in the ice making water tank 243 is supplied to the circulation pump 2

As shown by the solid line arrow, the circulation pipe 251 is raised,
It is led to the pressure chamber 213 above the water tray 209. The ice making water in the pressure chamber 213 extending in the width direction perpendicular to the paper surface flows into the ice making water passage 215, and is jetted from each of the fountain ports 207 into each of the ice making small chambers 205 as shown by arrows in FIG. Further flows down in the ice making water channel 215.
The ice making water injected into each ice making compartment 205 is the ice making compartment 2
Of the vertical and horizontal partitioning plates defining 05, the partitioning plate travels substantially parallel to the horizontal partitioning plate 203b, collides with the back wall 201c of the ice making chamber 205, and the flow is illustrated by a representative streamline. To spread. The ice making water that has flowed upward among the diffused flows flows almost along the inner wall of the ice making small compartment 205, and reaches the upper corner portion in the ice making small compartment 205, particularly the upper upper corner portion.

On the other hand, the ice making water 241c, which has flowed downward in the diffused flow, reverses as indicated by the arrow in the figure and flows toward the opening if it does not freeze, and a part of the water returns to the return port (FIG. (Not shown) from the return water guide path 2 as return water 242 (see FIG. 1) via a path different from the ice making water path 215.
29, and the rest is a horizontal partition plate 203b and a water tray 2
09 gradually flows down into the ice making chamber 205 one step below from the gap formed between the wall 211 and the wall 211. The ice making water is pumped into the ice making water channel 215 of the water tray 209 by the continuous operation of the circulation pump 249.
Ice making water is also supplied to the inside as described above.

On the other hand, a low-temperature and low-pressure refrigerant is introduced into the evaporator 217 attached to the outside of the inner wall 201c of the ice making chamber 201 from the upstream end communicating with the expansion valve. And
The refrigerant flows down the evaporator 217 and flows into each of the ice making chambers 2.
It absorbs the heat of ice making water in 05. As a result, FIG.
As shown in FIG. 3, the ice making water in each ice making small room 205 is made up of an ice making room outer frame 201a, an ice making room outer frame 201b made of a material having good thermal conductivity and an inner wall 201c close to the evaporator 217.

2 and the spring 239 itself is tilted clockwise around the upper shaft 227 as shown in FIG. Go. On the other hand, the cam lever 23
The lever piece 235 integrally fixed to the motor shaft 231 is also rotated by the same angle and in the same direction as the cam lever 233.
When the water tray 209 is fully opened as shown in FIG. 2, the switch 2 attached to the frame 225 is rotated.
37 is switched to stop the driving device (see FIG. 2).

In the de-icing step, hot gas flows into the evaporator 217 from the upstream end. As a result, the ice in each ice making compartment 205 is melted from the contact surface with the ice making compartment 205, and the horizontal partition plate 203b is inclined downward, so that it falls into an ice storage (not shown) by its own weight.

Thus, the de-icing step is completed, and the motor shaft 231 of the above-mentioned driving device rotates in the reverse direction.
Cam lever 233, spring 239 and lever piece 2
35 moves in a direction opposite to the movement described above, and the water tray 209 closes the opening of the ice making chamber 205 by the elastic force of the spring 239. At the same time, the tip of the lever piece 235 again switches the switch 237 provided on the frame 225, and the driving device stops (see FIG. 1).

As described above, the present invention is not limited to the above embodiment, and various modifications are possible. For example, as shown in FIG.
The water fountain port 207 may be formed in the water tray 209 of the ice making machine (see FIG. 11) having an ice making room in which the horizontal partition plate is not inclined downward. The fountain port 207 is provided on the wall 21 of the water tray 209 so that one fountain port 207 supplies ice making water to one ice making chamber 206 in the ice making chamber 202.
1 and its orientation and position are in the ice making compartment 206
Toward at least upwards in the horizontal direction, and
It is near the center of the opening of each ice making chamber 206, that is, on the center axis. Here, as in the above embodiment, the fountain port 207
Can be the optimum angle determined as a result of an experiment or the like that an area where ice is not made is the smallest or that no area is generated.

Another embodiment of the present invention is shown in FIG. The fountain port 307 is provided so that one fountain port 307 supplies ice making water to one ice making chamber 205.
Nine walls 311. The fountain port 307 is horizontal in its orientation, but the position provided on the wall 311 is the upper partition of the upper and lower partition plates of the ice making small chambers 205 to be sprayed by the fountain ports 307. This is a position close to the plate 203b. However, the degree of the proximity is set to an optimum distance obtained by an experiment or the like as in the previous embodiment.

Further, in the embodiment of FIG. 5, the ice making water from the fountain port 207 is supplied upward to the ice making chamber in which the partition plate is not inclined. However, as shown in FIG.
7 may be perforated in the wall 311 of the water tray 209 so as to supply ice making water to each of the ice making compartments 206 of the ice making compartment 202 substantially horizontally. That is, the direction of the fountain port 307 is oriented in the horizontal direction, and the position of the fountain port 307 is at a position close to the upper partition plate 204b of the upper and lower partition plates of each ice making small chamber 206 to be sprayed by the fountain port 307. is there.

The present invention can be embodied in various forms. For example, in all of the above-described embodiments, the fountain port is a linear circular passage having a uniform cross-sectional area from the inlet end to the outlet end of the ice making water. It is a preferable requirement, but not necessary, that the shape of the fountain port be linear or circular, since this is to eliminate an unmade ice area. For example, the outlet end of the fountain port may be processed to spray ice making water obliquely upward, or a guide may be provided at the outlet end to guide the ice making water obliquely upward.

As shown in FIG. 5, in a vertical ice making machine in which a horizontal partition plate 204b is provided horizontally, ice making water flowing into the ice making water passage 215 from the pressure chamber 213 is supplied to each of the fountain ports 207. It is injected into the ice making chamber 206. Then, in each ice making chamber 206, ice making water is supplied to the back wall 202c.
When the vehicle collides with the wall 202,
Since the ice making water collides with and spreads, the ice making water also spreads to the upper corner portion on the opening side in each ice making small chamber 206 where the ice making water was difficult to reach.

Further, as in the modified embodiment of the present invention shown in FIGS. 6 and 7, a fountain port is provided at a position close to the upper partition plate among the partition plates defining each of the ice making chambers. In the case of the ice making water, the ice making water jetted from the fountain port 307 flows from above the ice making small compartment 205 and the ice making small room 206, so that there is no area where the ice making water does not spread in each ice making small room, and the entire ice making small room is filled with ice making water. I do.
